I know you and I have discussed facebook ads, among other things already, and I do like what you have done with your facebook posts every now and then, but how many people do you think see those updates, that don't already actively visit this site (holy, run on sentence batman)? If you really want to grow the site, and are willing to put in some time (other that actually working on the site itself, which is great by the way) I think getting on twitter would definitely be to your (our) advantage.
My thinking is this: @PackersHome could follow everyone involving the Packers on twitter. Players, Coaches, Writers for the local newspaper, Packers Blogs, the "competing" Packers forums around, even noname packers fans. What would this accomplish? First, if a regular fan sees @PackersHome on their list of followers they are most likely going to follow back. That gets your name out there on a smaller level. Spending some time everyday, retweeting quotes from articles, or things the people, writers, or players are saying about the Packers. Retweeting things of common interest will get others to retweet the same things. That gets the PackersHome name out there on a much larger scale, and if your twitter profile is set up correctly, it will bring the site some new unique hits. If we're lucky, 5% of those new hits will result in new active members.
I could go much more in depth with this but I am 1) out of time and 2) I think that is good base to start with that you and the other could build some more on to.
The above would all be done without spending a dime, and without splattering the site with ads. All that would be needed would be a shift in your focus - from focusing on improving the site itself, to focusing on marketing the site for a while.
I would be more than willing to do the whole twitter thing for you, because I would love to see this site grow. But, I fully understand and expect that you would want to do that yourself, or at least have a hard time trusting someone else to represent your site in a matter in which you would approve.
If this should have been it's own thread, go ahead and separate it.
